[mkgmap-dev] building=house without addr:housenumber

Sun Jun 2 06:17:27 BST 2024

Hi all,

for OSM mapping purposes I like to have the possibility to add a poi for each residential (house,apartments,farm,...) building polygon that 
- doesn't have a addr:housenumber=* tag AND
- doesn't contain a node with addr:housenumber=* AND 
- doesn't have a node on the outline (part of the way) with addr:housenumber=* 

I want to render a POI with a text like "Hnr ?" so that, when I cycle near such a building, I can decide whether I try to find out the house number.

I think there is currently no way to do this with mkgmap since we don't have something like a "contains" style function. 
I can't remember if we even thought about this when the is_in function was added?

My current work around is to use JOSM as a preprocessor but that works only for small maps.
